iLoveIMG's bulk tools are genuinely well-reviewed, but the free tier runs on a monthly credit system — 2500 credits, and once that's used up, no more processing until the next billing cycle or a paid plan. Bulk Resize Photos avoids the credit cap, but a side-by-side test found that its output doesn't always land on the exact pixel dimensions requested — the tool preserves aspect ratio instead of honoring the target canvas size, which breaks workflows that need an exact size (marketplace listings, ad specs, print templates).
Batch image resizer online, with no monthly cap
This tool runs entirely on the Canvas API in your browser — there's no account, no upload, and no credit system to run out of. Drop in as many images as your browser's memory can hold and process them all in one pass.
Batch resize images without losing quality
A quality slider controls JPEG/WebP compression directly, and every processed file shows its before/after size right in the results list — so you can see the tradeoff before downloading instead of guessing. Files that don't need resizing or reformatting are passed through untouched rather than needlessly re-compressed.
Resize multiple images to same dimensions
"Exact size" mode forces every image in the batch to the same width and height you enter. "Fit within" mode instead keeps each image's own proportions and scales it down to fit inside a maximum size — useful when your source photos come in different aspect ratios and stretching them isn't an option.
Bulk convert images to WebP online, free
Set the output format to WebP (or PNG or JPEG) and every image in the batch converts at once, alongside the resize. No separate conversion step, and no per-file upload limit.
Resize photos for an online marketplace listing size
Many marketplaces and ad platforms require an exact pixel canvas (not just "under some size"). Because "Exact size" mode forces the literal width and height you set, there's no ambiguity about whether the output will actually match — every dimension is shown per file in the results list so you can confirm before downloading.
